What I'm trying to say is that for the average investor, what I would encourage them to do is to understand there's inflation and growth - it can go higher and lower - and to have four different portfolios essentially that make up your total portfolio that gets you balanced.

The expression I use: Pain + Reality = Progress. Whenever I would have a painful mistake, I started to view that as puzzles that would give me gems if I could solve the puzzle. So, it made me thoughtful - what should I do differently next time? That was the puzzle. And the gem was some principle for handling the same thing when it came along again, and then I would write it down. And by writing it down and referring to it, and also being able to show it to other people so that we could agree that that was a good way of handling that thing - that was very, very powerful.

I pay about a third in taxes, I give away about a third, and I follow the law.

Over time, it also became important for me to share my management principles with the people I worked with because we had to agree on how we should be with each other - and that way is unique. Because the logic behind being radically honest and radically transparent with each other wasn't clear, it had to be spelled out in these principles.

We wouldn't be successful if we didn't have independent thinkers who can argue and then resolve their arguments.

In return, society rewards those who give it what it wants. That is why how much money people have earned is a rough measure of how much they gave society what it wanted.

Forget about what the technology is. Just understand the motivation behind it.
